/**
 * Connects points in the order of the variable on the x-axis.
 * In the case points need to be connected in the order in which they appear in the data, use 'geomPath'.
 *
 * ## Examples
 *
 * - [lines.ipynb](https://nbviewer.org/github/JetBrains/lets-plot-docs/blob/master/source/kotlin_examples/cookbook/lines.ipynb)
 *
 * - [error_bars.ipynb](https://nbviewer.org/github/JetBrains/lets-plot-docs/blob/master/source/kotlin_examples/cookbook/error_bars.ipynb)
 *
 * @param data The data to be displayed in this layer. If null, the default, the data
 *  is inherited from the plot data as specified in the call to [letsPlot][org.jetbrains.letsPlot.letsPlot].
 * @param stat The statistical transformation to use on the data for this layer.
 *  Supported transformations: `Stat.identity`, `Stat.bin()`, `Stat.count()`, etc. see [Stat][org.jetbrains.letsPlot.Stat].
 * @param position Position adjustment: `positionIdentity`, `positionStack()`, `positionDodge()`, etc.  
 *  see [Position](https://lets-plot.org/kotlin/-lets--plot--kotlin/org.jetbrains.letsPlot.pos/).
 * @param showLegend default = true.
 *  false - do not show legend for this layer.
 * @param inheritAes default = true.
 *  false - do not combine the layer aesthetic mappings with the plot shared mappings.
 * @param manualKey String or result of the call to the `layerKey()` function.
 *  The key to show in the manual legend. Specifies the text for the legend label or advanced settings using the `layerKey()` function.
 * @param sampling Result of the call to the `samplingXxx()` function.
 *  To prevent any sampling for this layer pass value `samplingNone`.
 *  For more info see [sampling.html](https://lets-plot.org/kotlin/sampling.html).
 * @param tooltips Result of the call to the `layerTooltips()` function.
 *  Specifies appearance, style and content.
 * @param x X-axis value.
 * @param y Y-axis value.
 * @param alpha Transparency level of a layer.
 *  Understands numbers between 0 and 1.
 * @param color Color of the geometry.
 *  For more info see: [aesthetics.html#color-and-fill](https://lets-plot.org/kotlin/aesthetics.html#color-and-fill).
 * @param linetype Type of the line.
 *  Accept codes or names (0 = "blank", 1 = "solid", 2 = "dashed", 3 = "dotted", 4 = "dotdash", 5 = "longdash", 6 = "twodash"),
 *  a hex string (up to 8 digits for dash-gap lengths),
 *  or a pattern `offset to listOf(dash, gap, ...)` / `listOf(dash, gap, ...)`.
 *  For more info see: [aesthetics.html#line-types](https://lets-plot.org/kotlin/aesthetics.html#line-types).
 * @param size Line width.
 * @param colorBy default = "color" ("fill", "color", "paint_a", "paint_b", "paint_c").
 *  Defines the color aesthetic for the geometry.
 * @param mapping Set of aesthetic mappings.
 *  Aesthetic mappings describe the way that variables in the data are
 *  mapped to plot "aesthetics".
